Said rings preterably fit the pipe tightly so that they may be adjustable thereon. The lower pipe 29 has mounted thereon two small pans 37 and 38.

each disposed beneath one of the openings 32. The pans have a bail 39 secured at each end by means of which they may be held securely against the pipe 28. The pans are filled with asbestos and may rest on the grate 31, thereby supporting the gas gener ating pipe and burner on the grate.

The parallel members 27 and 28 are connected at one end by the unobstructed passage-way 40 which constitutes a gas chamber. Said arms 27. 28 are each open at their other end. The lower pipe 28 is closed at its open end by a cap 41.. The open end of the upper pipe 27 is coi.nected to the nozzle 17 by means of elbows 49 and 43 and the nipple 44. the outer end of the. nozzle l7 having external threads thereon to accommediate the elbow 3 and the end of the pipe 27 being similarly threaded to receive the elbow 42. fine Wire gauze, mineral wool or ineombnstible porous material 45.

thoroughly mixed and moisture will he removed therefrom. The upper pipe 27 is partially filled with light wires 46 to more uniformly distribute the heat and prevent the flame from overheating the pipe at any aid chamb-r and having a perforate perpoint. This wire also provides a larger area for the accommodation of the, residue or non-combustible material resulting from the decomposition of the oil. The lower pipe 28 is partially filled wi h large or'heavy wire 48 for further mixing of the gas and even distribution of the same. When it is desired to clean the arms ot the pipes the said wires may easily be removed through the open ends of the pipes by unscrewing the elbows 42 and 43, and cap The operation of the burner will be clear from the foregoing description. The oil and air is discharged under pressure into the primary mixing chamber 10 from tank T. It is thoroughly mixed in this chamber and then passes into the vaporizing device through the mixing an cleaning pipe 44.

The jet issuing from the openings 32 is ignited. The flame from the burning oil will heat the pipe 27, vaporizing the mixture of oil and air therein. whereupon combusti ble gas instead of oil will issue from the- The nipple 44 is filled with 1 The oil and gas passing through this material will be more heat.

By thoroughly mixing the oil and air under pressure before vaporizing the same in the retort I am able to obtain more heat from a given quantity otoil and a brighter and clearer flame. doing away with smoke and the like. The U-shaped vaporizer and burner is more readily kept free trom noncombustible material and from overheating.

It will be seen that l have provided a sim ple and etiicient device for the purpose described and as changes within the scope of the claims may be made without departing from the spirit of tin invention. I do not: wish to limit myself to the exact details as shown and described.

Having thus des ribed my inv ntioinwhat l claim is:

l. in a device of the class described. the m ination with a mixing chamber tcr oil and air. of a gas mixing and generating pipe communicating with aid hambcrfa portion f said pipe having tuel jet open ings therein adapted to di e t the jet ot fluid toward the inipertorat" portion ot the pipe. and means within the erforate and in'iperforate portion ol' said pipe to further mix the oil and air.

2. ln a device of the class de cribed. the combination with a mixing chamber for oil and air under pressure. of a gas mixing and generating pipe communicating with tion to provide an opening for the escape of fuel under pressure. an imperi'orate. portion disposed above said ptwt rate portion. means on the inipcri'orate portion adapted to distribute the heat and tlame caused by the ignited jet. of fuel issuing from the said opening, and loose metal strips in both the impertorate and perforate portions of aid pipe. to further mix tln oil and air and intercept inconiluistihle matter.

3. Tu a device of the class described. the combination with a mixing chamber for oil and air adapted to he supported outside the fir box of a. heating device. of a con tinuous gas mixing and generating pipe and burner disposed within the llIOlmX and communicating with the said chamber. a portion of said pipe having openings therein adapted to direct jets oi the fluid toward the imperforate portion of the pipe. means in the imperi'orate portion for liliX- ing and cleaning the mixture of air and oil delivered trou: the mixing chamber on the outside of the heating device. and means in the perforate portion for further mixing the gas.

4. In a device of the class described. the

combination with a. combustion chamber the Wall of which is provided With an opening, of a mixing chamber for oil and air sup ported on said wall outside the combustion chamber, a nozzle communicating with said mixing chamber and projecting and dis charging through said opening, a gas generating pipe disposed within the combustion chamber having a discharge opening therein. a pipe connecting the generating pipe with the end of said nozzle pro ecting through sairl opening in the combustion chamber wall. and a perforate non-combustible material in said connecting pipe to further mix the air and oil and clean the same.

in a device of the class described. the combination with a mixing chamber for oil and air, of a continuous U-shaped pipe constituting a retort. one of the arms of which pipe is provided with perforations facing the other arm to direct the tluid eacaping therefrom toward the latter, a pipe connecting the iu'ipcrt'orate portion of the retort with the mixing hamber, and means in said pipe to further mix and clean the mix ture of air and oil.

in a device of the lass described. the

combimition with a mixing chamber for oil and 111. of a vertu'allv dispmed onepiece 1 U-shapcd retort. one of the a rm being per foratc and the other foratiom adapt d t ing therefrom toward .aal impcrl'orate arm. a. pipe conne'zting the end of thc impert'orate arm with the mixing chamber. said pipe having wire gauze therein to further mix and clean the air and oil.

a plurality oft iniperforate, the er- 1 direct th thud csca r wires in the imperforate arm and a plurality of wires in the perforate portion, the portion of the retort corresponding to the bend of the U being unobstructed.

7. In a device of the class described, the combination with a combustion chamber, the wall of which provided with an opening of a mixing chamber for oil and air supported on said wall. a nozzle communicating with said chamber and discharging through said opening. an oil and air mixing and gas generating retort arranged in the combustion chamber to receive fluid dis charged from said nozzle, a tapering valve for said nozzle having a circumferential groove immediately back of the tip curved in longitudinal section, and a tapering seat for said valve.

8. ln a device of the class described, the combination with a combustion chamber the wall of which is provided With an opening,

of a mixing chamber for oil and air sup ported on the wall outside the combustion chamber, a nozzle conununieating with said mixing chamber and discharging through said opening, a generating pipe disposed within the comhustion chamber and arranged to rereive fluid discharged from said nozzle. aaid pipe having perforate and impert'orate portions. and loose metallic material in said portions to mix the oil and air and intercept incombustible matter.

ln testimony whereof I attiX my signature in presence of two witnesses.
